We have not yet independently confirmed their authenticity, but everything revealed in the slides sounds and looks reasonable, though, the appearance of an Autobild magazine render of the Macan, does raise some questions.

The first piece of information concerns the introduction of new GTS versions of the Porsche Cayman coupe and Boxster roadster models, with features said to include a 15-horsepower bump for a slightly faster 0-60mph (96km/h) sprint time, Sport Design front and rear fascias, 20-inch Carrera S wheels, upgraded steering wheel, and leather interior. It is mentioned in the slide that the two models will break cover at the Beijing Auto Show in China next April (2014).

Next up is the all-new Porsche 911 Targa, which we have spied mostly undisguised more times than once. According to the (alleged) presentation, the Targa will have a "Fully automatic roof system to satisfy customer demands for comfort". We're not sure how this will work given that the new Targa will feature a similar center pieces as the classic version of the car. The snapshot of the slide says that it will be available in both Carrera 4 and Carrera 4S trims.
